application filed June- 5,

To all wit-m it may concern:

Be it known that l, Bonner HIsLor, a citizen of the United States, residing at Racine, county of Racine, State of Wisconsin. have invented a certain new and useful improvement in Candy-Making Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for the manufacture of candy, such as chocolates or the like, or of small cookies, cakes, or similar articles which can be formed from semi-liquid or plastic material and hardened by cooling, drying, or baking. Although applicable to machines of other types, the invention is herein shown as applied to and embodied in a chocolate dropping machine of the character shown in Letters Patent No. 791,611, granted June 6, 1905. to Joseph M. Demerath and a further developmentof which is described in the application for Letters Patent filed Nov mber 15, 1920. by Willis N. Hartshorn, Serial No. 124,013.

The present invention has for its object to provide means whereby cakes or contcctions having an ornamental form and appearance may be conveniently, rapidly and economically produced, without the use of molds. by mechanism operating upon the dropping or depositing principle.

To this end the invention, in its pre ferred form, comprises a nozzle or equiva-- lent device adapted to deposit measured quantities of the plastic material upon a receiver or carrier having a flat surface, said nozzle having an orifice which, as a whole, is preferably of non-circular but symmetrical form, means being provided for oscillating or turning said nozzle on its axis at a predetermined time during the depositing operation. whereby the confection produced will have a more or less twist ed or spiral form. The mechanism also operates in proper time relation with the up and down movement of a table on which the goods are deposited, this movement being desirable to taper off the top of the piece of goods which is being produced.

The foregoing object of the invention, together with means whereby the same may be carried into effect, will best be under- 1922. Serial No. 565,916.

stood from the following description of one form or embodiment thereof illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevation, partly broken away, of so much of the machine as is nececto an understanding of the invention.

Fig. 2 is an elevation, partly in section on the line 2 2, Fig. 1, of one end of the upper portion of the machine shown in the latter figure.

Fig. 3 is a section taken substantially on the line 3-8, Fig. 2.

Fig. a is a horizontal section taken sub stantially on the line 4, Fig. 3.

Figs. 5, 6, 7 and 8, and 9, 10, 11 and 12 are detail views in plan and elevation re spectively of several forms of confections capable of being made by the machine.

Figs. 13, l-i, 15 and 16 are bottom plan views respectively of the nozzles by which these confections are formed.

As in the patent and prior application above preferred to, the machine frame 15 is arranged to support a hopper or reservoir 16 adapted to contain a quantity of plastic or semi-liquid material, such as a melted chocolate compound. At its bottom, the reservoir or hopper 16 communicates with a transverse series of nozzles 17, said communication being controlled by a combined measuring and ejecting valve device 18 which may be substantially as shown and de scribed in said Demerath patent. The valve device 18 is enclosed by a casing 26 at the bottom of the hopper 16 and has a port communicating therewith, said casing and hopper being preferably formed with hollow jackets for the circulation of a heating fluid. Below the hopper 16 and nozzle 17 is a carrier or receiver 14 for the material deposited by said nozzles. said carrier being moved intermittently. between the deposit ing operations, to receive fresh deposits from the nozzles 17, by means of a chain or chains 19 passing over sprockets 20 at the ends of the machine and actuated by suitable intermittent feeding mechanism. Said carrier may be as indicated in the drawings in the form of a continuous flexible sheet metal belt having a polished surface. as described in the Hartshorn application above referred to, or it may comprise a series of trays one of which is shown in dot and dash lines at i orm protuberances 48 at the edges thereof. As the nozzle is turned, the material of the protuberances 48 will be twisted into a spiral form. The semi-fluid condition of the material causes the mass deposited to spread upon the surface of the carrier 14, and toward the end of the operation, after the greater portion of the mass has been ejected through the nozzles, the carrier 14 is lowered, increasing the distance between it and the orifices of the nozzles, and thereby causing the material to be drawn up and tapered in conical shape, as shown in Figure 10. The viscosity of the material at this time causes the portion thereof last to leave the nozzle to be drawn into a stream or thread of decreasing diai'neter, so that the material of the protuberances 48 is drawn inwardly over the top of the body 47 to form spiral ribs which meet substantially in the center of the top of the confection.

The nozzle 170 shown in Figure 13 is substantially similar to the nozzle 17 shown in Figure 10, the central orifice thereof being, however, formed with a greater number oi radial extensions 460 each of which is of less width than the extensions 46 of the nozzle 17, so that the body 470 of the confection shown in Figures 5 and 9 is provided around its periphery with a considerable number of thin radial protuberances 480 from which extend, over the top of the body 470, a corresponding number of spiral ribs 490 meeting at the top of the body in the center.

The nozzle 171 shown in Figure 15 is provided with a series of eccentric supplementary orifices 461, being connected by comparatively narrow slots 462. The body 471 out the confection formed by this nozzle, as shown in Figures "7 and 111, is surrounded by a series of more or less distinct bodies 481 which, however, by reason of the spreading of the material, are more or less merged with the main body 471, said supplementary bodies 481 being connected at the top of the ma in body 471 by spiral ribs 491.

in the nozzle 1'? 2 shown in Figure 16, the central discharge orifice is omitted, and the nozzle is provided with a plurality of eccentric orifices 463 symn'ietrically arranged about the center of the nozzle. As shown in Figures 8 and 12, the material deposited by the orifices 463 will form a corresponding number of separate bodies 482, which, due to the spreading of material, will be more or less merged with one another, and each of which is provided with an extension 492 which drawn out into spiral form over the next adjacent body and toward the. center of the confection as a whole.

The above-described specific "forms which the nozzles may assume, and the shapes of the confections formed thereby, are merely illustrative of the invention, and it will be obvious that the form of the nozzle may be varied almost without limit, and that the shapes of the confections will be correspondingly varied. A

The amount of twist given to the spiral ribs 49, 490, etc., will be controlled by the amplitude of oscillation of the nozzles 17, this being, in turn, determined by the point oi? connection of the rod 41 with the arm 38. The time with respect to the time of opera-- tion of the valve device 18, at which the twisting takes place, as controlled by the adjustment of the eccentric will determine to a considerable extent the shape of the protuberances or bodies 48, 480, etc, with re spect to the ribs 49, 490, etc. Thus, by comparison of Figures 6 and 7, it will be seen that in the formation of the confection shown in Figure 7, the turning movement oi the nozzle commenced earlier in the deposit ing operation than in the case of the confection shown in Figure 6, so that the bodies 481 have been, to a certain extent, elongated circumferentially oi the body 471. prior to the formation of the ribs 491. whereas in the formation of the confection shown in ure 6, the bodies 48 are not elongated circunii erentially, the twist being substantially confined to the ribs 49. In the contention shown in Figure 5, the twist is also substantially confined to the ribs, the projections 480 being merged almost immediately into the ribs 490. From the foregoing it will be seen that the shapes produced by the machine may be varied, not only by changing the nozzles, but by different adjustments of the mechanism with the same nozzle.

What I claim is z 1.
